When using RSS on 9000 series devices, we can't rely on processing the
received frames for station powersave handling, since they could be
processed on different CPUs and out of order.
In order to still manage the powersave of stations, the firmware sends
a notification on sleep->wake, wake->sleep and - for U-APSD - frames
received with PM while already sleeping (with the TID.)
With this, the driver can set AP_LINK_PS, which is required for real
parallel RX. In addition, this requires checking for PS-Poll frames
and calling ieee80211_sta_pspoll() appropriately.

In order to access cached/paged memory, there are a couple of firmware
commands (one for UMAC and one for LMAC) that let the host access memory
and registers indirectly. Since this is done by the firmware on behalf
of the host, even if memory is paged out or cached, the host will
retrieve the memory as the firmware sees it (paged out memory will get
paged in).
Export this mechanism via a debugfs entry for both read and write
access.
WARNING: This mechanism has no protections at all. Invalid addresses may
crash or hang the firmware. Writing to arbitrary memory also comes with
no guarantees.

In a000 devices we have 15 fifos, so in the shared memory
config the number of tx fifos in the array was changed
accordingly.
As it is in the middle of the struct, the parsing code needs
to be duplicated.
To minimize the duplication, do not save variables we never
actually use.

Add support CSA countdown offloading. When CSA starts, the driver
specifies the offsets to the eCSA and CSA IEs in the beacon template
command and the fw performs the countdown.
The fw notifies the driver when the channel switch flow
should be performed.
Beacon sent notifications are not used anymore.

"DQA" is shorthand for "dynamic queue allocation". This
enables on-demand allocation of queues per RA/TID rather than
statically allocating per vif, thus allowing a potential
benefit of various factors.
Please refer to the DOC section this patch adds to sta.h to
see a more in-depth explanation of this feature.
There are many things to take into consideration when working
in DQA mode, and this patch is only one in a series. Note that
default operation mode is non-DQA mode, unless the FW
indicates that it supports DQA mode.
This patch enables support of DQA for a station connected to
an AP, and works in a non-aggregated mode.
When a frame for an unused RA/TID arrives at the driver, it
isn't TXed immediately, but deferred first until a suitable
queue is first allocated for it, and then TXed by a worker
that both allocates the queues and TXes deferred traffic.
When a STA is removed, its queues goes back into the queue
pools for reuse as needed.

LQM stands for Link Quality Measurement. The firmware
will collect a defined set of statitics (see the
notification for details) that allow to know how busy
the medium is. The driver issues a request to the firmware
that includes the duration of the measurement (the firmware
needs to be on channel for that amount of time) and the
timeout (in case the firmware has a lot of offchannel
activities). If the timeout elapses, the firmware will
send partial results which are still valuable.
In case of disassociation / channel switch and alike, the
driver is in charge of stopping the measurements and the
firmware will reply with partial results.
The user space API for now is debugfs only and will be
implmemented in an upcoming patch.

When the device is in d0i3/d3 we will not receive the VHT
MU-MIMO group id management frame. Instead, firmware will
notify us upon exit on the current status and we can in turn
update mac80211. Support this notification.
While at it, also check as a precaution that the vif is indeed
the VHT MU-MIMO owner before updating the firmware.

In multi rx queue HW, without execessive locking, there is no sync
between the ctrl path (default queue) and the rest of the rx queues.
This might cause issues on certain situations. For example, in case
a delBA was processed on a default queue but out of order packets
still wait for processing on the other queue.
The solution is to introduce internal messaging between the CTRL path
and the other rx queues.
The driver will send a message to the firmware, which will echo it to
all the requested queues. The message will be in order inside the queue.
This way we can avoid CTRL path and RSS queues races.
Add support for this messaging mechanism. As the firmware is agnostic to
the data sent, add internal representation of the data as well.
Although currently only delBA flow will use it, the internal representation
will enable generic use of this infrastructure for future uses.
Next patch will utilize this messaging mechanism for the reorder buffer
delBA flow.

Currently firmware is configured to filter out beacons. In case
a beacon was changed - it is waking the host.
However, some vendors change their IEs frequently without any
significant change, and redundant wakeups are triggered as a
result.
As a solution disable beacon filtering when entering d0i3.
Instead, firmware will store the latest beacon and upon exiting
d0i3 it will send it up to the host, so the host can act upon
changes (if there were any).
This beacon will arrive as a dedicated notification - support it
as well.
